Abstract (en)

[origin: EP2784552A2] Methods (600, 1100) and devices (1200) for seismic data processing attenuate noise by replacing an attribute value v(i) of a selected data point (700) i with a weighted average v(i) of attribute values of data points j from a window (710) that includes the selected data point i. The contribution to the weighted average of an attribute value v(j) corresponding to a data point j depends on how similar attribute values in the neighborhood N j of the data point j are to attribute values in the neighborhood N i of the selected data point i.
